What is the shunt resistance \(S\) needed if the galvanometer current \(I_g\) is \(8\%\) of the total current \(I\)?
A wire of length 2 m and resistance 8 \(\Omega\) is stretched to double its original length, keeping the volume constant. What is the new resistance of the wire?
A wire has a resistance of \( 10 \, \Omega \) at \( 20^\circ \text{C} \). If the temperature coefficient of resistance of the material is \( 0.004 \, \text{per}^\circ \text{C} \), what is the resistance of the wire at \( 50^\circ \text{C} \)?
The resistance of a wire is \( 10 \, \Omega \) and the current passing through it is \( 2 \, \text{A} \). What is the potential difference across the wire?
A 5-ohm resistor is connected to a 10 V battery. Calculate the current flowing through the resistor.
In a meter bridge experiment, a resistance of \( 10 \, \Omega \) is balanced by a resistance \( X \) with a balance point at \( 40 \, \mathrm{cm} \). What is the value of \( X \)?
From current electricity, to convert a galvanometer into an ammeter, a shunt is given. Find the resistance of the galvanometer.
A wire of length 3 m connected in the left gap of a meter-bridge balances 8$\Omega$ resistance in the right gap at a point, which divides the bridge wire in the ratio 3: 2. The length of the wire corresponding to resistance of 1$\Omega$ is
